CARBURETOR ADJUSTER AND GASOLINE-LINE-LOCKING DEVICE.

Application filed December 26, 1923.

The invention is a means for adjusting the carburetor from the instrument board of a motor vehicle which may also be used to shut oil and lock the gasoline supply line,

The object or" the invention is to provide a simple and etfieient means for adjusting the carburetor of a motor vehicle which may be operated from the instrument board.

Another object of the invention is to provide a means for adjusting the carburetor from the instrument board whichmay be made of one piece of material.

And a further object of the invention is to provide a means for adjusting the carburetor "from the instrument board which may also be used to lock the gasoline sup ply line, either entirely closed or in different adjustments.

With these ends in view the invention embodies a curved bar having a handle at one end, two prongs at the other, and a loop for holding it.

Other features and advantages of the invention will be seen from the following description taken in connection with the drawings, wherein Figure 1 is a sectional View showing the device.

Figure 2 is a section showing an alternate arrangement in which a block of wood is shown behind the instrument board which is common in enclosed vehicles.

Figure 3 is a view showing another alternate arrangement.

Figure 4; is a View showing an alternate arrangement in which a loop is provided in the bar so that it may be lengthened or shortened.

Figure 5 is an alternate design showing the lower end of the bar flattened and placed in a slot in the upper end of the carburetor adjusting stem.

Figure 6 is a view showing an alternate arrangementin which the lower end of the bar is flattened and placed between two fiat plates at the upper end of the carburetor adjusting stem.

Figure 7 is a view showing an alternate arrangement in which the bar is flattened and bolted to the upper end of the carburetor adjusting stem,

Figure 8 is a view showing an alternate arrangement in which the loop 8 bears against a bracket at the dash board.

Figure 9 is a view showing an alternate Serial No. 682,706.

arrangement in which a section of the dash board is stamped on an angle.

In the drawings I have shown my device as it would be constructed wherein numeral 1 indicates the bar, numeral 2 a carburetor, and numeral 3 an instrument board.

The bar 1 may be constructed as shown and curved so that it will pass directly backward from the instrument heard, through an opening 1 in the dash board 5 and then curved downward so that it will come directly down on the axis of the needle valve of the carburetor. The upper end of the bar extends through an opening 6 in the instrument board and is then bent at an angle to form a handle 7. The bar may be provided with a loop 8 which may bear against the under side of the instrument board as shown in Figure 1 and this loop which may be welded at the point of intersection of the bars may be arranged so that the yoke of a lock may pass through it and through an opening 9 in the instrument board which will make it possible to lock the device at the instrument board. This loop may also be placed in a position adjacent the dash board 5 so that it may bear against the under side of a bracket 10' as shown in Figure 8 so that the rod may be held downward from the dash board. It is also understood that the bracket 1O may be omitted and a section of the dash board stamped on an angle as shown in Fig ure 9 and indicated by the numeral 11 so that the yoke 8 may bear against its under side in order to hold the bar downward. The lock shown in Figure 1 may be used to lock the bar 1 through the loop 8 in either of the designs shown in Figures 8 and 9 by placing the yoke of the look through the loop and through openings in the bracket or dash board.

The designs shown in Figures 2 and 3 comprise alternate arrangements for holding the upper end of the bar at the instrument board. In Figure 2 the loop 8 is replaced by a U bond 12 which is particularly adaptable for enclosed cars but may be used with the type of instrument board shown in Figure 1. It will be seen that the lock may be used with this design by placing the yoke through the U bend and through an opening 9 in the instrument board. In Figure 3 a straight bar 13 is used for holding the bar 1 upward and this bar is rigidly attached to the bar 1 needle valve stem of the carburetor. Or this enc may he held in place by a lock 16 as shown in Figure 1. ii loop 1 as shown in Figure may he provided at the lower end of the her so that it will he possible to lengthen or shorten the bar by increasing or decrc ing the size of the loop. This loop in: also be used to lock the device as the lock 16 may be placed through it as shown.

In Figures 5, 6, and 7 l have shown alternate means for attaching the lower end oi the b: r 1 to the needle valve stem. in each of these designs the lower end of the har 1 is flattened as shown and this flattened section, as indicated by the numeral 18, may be placed through a slot in the hair 15 as shown in Figure 5, or ")lace'd between two flat plates as shown in Figure (5, or oolted to a section 20 at the upper end oi the valve stem by bolts 21 as shown in Figure 7. The section 18 may be provided with an opening "n the design shown in Figure 5 so that a pin or loch may be placed through it to hold it in place. A similar opening may be placed through the flatsections shown in Figures (3 and 7 so that pins 1' locks may be placed through them to hold them in place. It i: also understood that either of the designs shown or any other suit-a *le means may be used for holding the lower end of the bar to the needle valve stem.

The construction will be readily understood from the foregoing description. To use the device it may he installed in a car by placing the rod 1 through an opening t in the dash board, attaching its lower end a -1,aes,see

to the needle valve stem of the carburetor in any in. able n and attaining its upper end to the instrument heard in any suitable manner. It will then be seen that by tn the handle 7 of the bar it will be possible to rotate the needle valve. And it will also be seen that the needle valve may be adjusted to any suitable position, which may provide a proper mixture or which may close the valve, and that the lower end of the red may be attached to the stein in such a manner that when the valve is closed the upper end 0t the rod will be in the position shown so that the lock may hold it. This will make it possible to locl: the needle valve in a plurality of open positions or completely closed as may be desired. ll Y removing the locl: at the upper end it ill he l J .l caiouretor .Llviil inc n Mistin the hand y escrihed the inve .c, 1 lili maving ti u.
